Web1. The perimeter of a square is the sum of the lengths of all its sides. If a side of the square measures 2 cm, then the perimeter is 4 times the length of one side, or 4 x 2 = 8 cm. Therefore, the perimeter of the square is 8 cm. 2. If a side of the polygon measures 3 cm, then we need to know how many sides it has in order to find its perimeter.
